JONAS F. WILE, OF NEW PITTSBURG, OHIO.

BLlND-SLAT ADJUSTER.

SPECIFICATION forming part of Letters PatentNo. 227,937, dated May 25, 1880.

Application filed March 5, 1880.

To all whom it may concern Be it known that I, JONAS F. WILE, of New Pittsburg, in the county of Wayne and State of Ohio, have invented certain new and useful Improvements in Blind-Slat Adjusters; and I do hereby declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference beinghad to the accompanying drawings, which form a part of this specification.

Figure 'l is a perspective view. Fig. 2 is a vertical sectional view; and Fig. 3 is a crosssection.

Corresponding parts in the several figures are denoted by like letters of reference.

This invention relates to devices by which the slats of exterior window-blinds may be adjusted so as to admit more or less light, and retained in the desired position without raising the sash; and it consists in the improved construction of the same, which will be here inafter more fully shown and described, and particularly pointed out in the claims.

In the annexed drawings, A represents the window-frame, and B U the upper and lower sashes, which, in Fig. 1, are shown in dotted lines only, so as not to obscure the view of my invention.

D is the blind-frame, which is provided with the pivoted adjustable slats E, connected by a vertical rod, F, in the usual manner. If the blind consists of two or more sections the several connecting-rods may be joined by sheetmetal couplings G, as shown.

H is a lever pivoted to the lower end of the blind-frame between the side and center. and having one end connected to the lower end of rod F. At its other outer end the lever H is provided with a stud, I, having a transverse perforation, J. I The under side of the outer end of lever H is also provided witha stud, K, adapted to enter any one of a series of (No model.)

openings, L, in a plate, M, secured upon the blind-frame under the end of the lever. The lattershould be sufficiently elastic to permit its being raised sufficiently to transfer the stud K from one to another of the openings L.

The frame of the lowersash is provided with and desire to secure by Letters Patent of the i United States 1. The combination of the blind B, having slats E, connecting rod or rods F, centrallypivoted elastic or spring lever H, having one end'connected to said connecting-rods and the other provided with a stud, K, and the perforated plate M, substantially as and for the purpose set forth.

2. The combination of the blind 13, having pivoted slats E,connecting rod or rods F, centrally-pivoted elastic or spring lever H, having one end connected to said connectingrods and the other end provided with a stud, K, and transversely-perforated stud I, perforated plate M, sash (3, having perforation N, and the hooked rod or key P, substantially as and for the purpose set forth.

In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two witnesses.

JONAS F. WILE.
